With Tecton, you can confidently author CSS using a statically-typed language, protecting you from a wide range of CSS errors—some rather obscure. I built Tecton after finding other statically-typed CSS solutions to be cumbersome and outdated, limited to subsets of CSS that would not meet the needs of most real-world projects. On the other hand, Tecton uses advanced features of PureScript to deliver a familiar, flexible, and reliable CSS authoring experience.
